Key Science Goals

Detection of terrestrial exoplanets in the habitable zone of solar-type stars and characterization of their bulk properties needed to determine their habitability.

  • Characterisation of thousands of rocky (including Earth twins), icy or giant planets, including the architecture of their planetary system, to fundamentally enhance our understanding of the formation and the evolution of planetary systems.
  • These goalswill be achieved through:
    • planet detection and radius determination (2% precision) from photometric transits;
    • determination of planet masses (better than 10% precision) from ground-based radial velocity follow-up,
    • determination of accurate stellar masses, radii, and ages(10% precision) from asteroseismology,
    • identification of bright targets for atmospheric spectroscopy.
